Climate‐driven elevational variation in range sizes of vascular plants in the central Himalayas: A supporting case for Rapoport's rule

Ecology and Evolution, 2021
A fundamental yet controversial topic in biogeography is how and why species range sizes vary along spatial gradients. To advance our understanding of these questions and to provide insights into biological conservation, we assessed elevational ...

Changes in the structure and composition of the 'Mexical' scrubland bee community along an elevational gradient.

PLoS ONE, 2021
'Mexical' scrubland is a sclerophyllous evergreen Mediterranean-like vegetation occurring in the leeward slopes of the main Mexican mountain ranges, under tropical climate.

The species richness and community composition of different growth forms and life forms of mosses are dominated by different factors along an elevational gradient of China

Global Ecology and Conservation, 2023
Understanding the elevational variation in species richness and community composition as well as their mechanisms is critical for biodiversity conservation.

Biomass, abundances, and abundance and geographical range size relationship of birds along a rainforest elevational gradient in Papua New Guinea [PDF]

PeerJ, 2020
The usually positive inter-specific relationship between geographical range size and the abundance of local bird populations comes with exceptions. On continents, the majority of these exceptions have been described from tropical montane areas in Africa,

Bird diversity of the Amrutganga Valley, Kedarnath, Uttarakhand, India with an emphasis on the elevational distribution of species [PDF]

Check List, 2016
A unique aspect of montane birds is the elevational stratification they show in their distribution, but in the Himalayas, a subset of the species show elevational migration, making bird communities on these mountains especially dynamic.

Conservation status affects elevational gradient in bird diversity in the Himalaya: A new perspective

Global Ecology and Conservation, 2014
Understanding diversity patterns along altitudinal gradients, and their underlying causes are important for conserving biodiversity. Previous studies have focused on climatic, energetic, and geographic variables (e.g., mid-domain effects), with less ...

Different mechanisms driving increasing abundance of microbial phosphorus cycling gene groups along an elevational gradient

iScience, 2022
Summary: Microbes play an integral role in forest soil phosphorus (P) cycling. However, the variation of microbial P-cycling functional genes and their controlling factors in forest soils is unclearly.

Divergent changes in the elevational gradient of vegetation activities over the last 30 years

Nature Communications, 2019
Climate change may lead to changes in elevational patterns of vegetation activitities. Here, the authors analyze global remotely sensing data collected during 1982–2015 to investigate the spatio-temporal dynamics of the elevational gradient in vegetation

Loss of proton‐sensing TDAG8 increases tumor progression in mouse models of colon cancer

Molecular Oncology, EarlyView.
Loss of the pH‐sensing receptor TDAG8 accelerates colorectal cancer progression in mice. Animals lacking TDAG8 expression had increased tumor growth, DNA damage, and recruitment of tumor‐associated immune cells, including macrophages, neutrophils, and monocytes.
